Answer 1

您既可以扩展应用程序类，也可以直接在web.xml中提供提供者和资源列表。

方法1：使用应用程序类

来自泽西岛文档：

  Example 4.11.  Configuring Jersey container Servlet or Filter to use custom Application subclass      
   <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>org.foo.MyApplication</param-value>  
  </init-param>

例4.12。配置Jersey容器Servlet或过滤器以使用包扫描

<init-param>
    <param-name>jersey.config.server.provider.packages</param-name>
    <param-value>
        org.foo.myresources,org.bar.otherresources
    </param-value>
</init-param>
<init-param>
    <param-name>jersey.config.server.provider.scanning.recursive</param-name>
    <param-value>false</param-value>
</init-param>

我的首选是使用应用程序，因为它可以用来设置其他泽西属性以及。

如果上述设置不起作用，请提供您的应用程序pom.xml和web.xml。
